I need to know which rear end carrier I have. I want to put 3.73's in my z/28 auto. What do I do to figure out if I have the series 2 or 3 carrier?

 

problem solved...

 

What happened to "body work first"?? lol

 

I was just curious hahaha come on... I was tryin to figure out what gears it had already cause after the body work gears and headers are next. The body work will be easy anyways its not that much at all. Just a new RF fender and paint of course.

 

You got 2.73's?

 

Well not necessarily. If his car is a 6-speed then he has 3.42's

 

He says he's got a automatic.

 

Then yes 2.73's

 

I looked up the RPO code and its the 3.23's .They were available with the auto trans too. At least in 96. GU5 is the code. https://camaroforums.com/forum/93-02-general-41/93-02-f-body-rpo-codes-50977/

 

So i have the 3.08 and up carrier then if im not mistaken. So that means the series 3.
